3.3.4 Data Transfer Speed

Figure 11. Data Transfer Speed

Instantaneous Disk-Buffer Transfer Rate (Mbyte/sec) is derived by:

(Number of Sectors on a track) * 512 * (Revolution/sec)

Note: Number of sectors per track will vary because of the linear density recording.

Sustained Disk-Buffer Transfer Rate (Mbyte/sec) is defined by considering head/cylinder change time.
This gives a local average data transfer rate. It is derived by:

(Sustained Transfer Rate) =

A/ ( B + C + D )

A =

(Number of Data Sectors per Cylinder) * 512

B =

(# of Surface per cylinder) - 1) * (Head Switch Time)

C =

(Cylinder Change Time)

D =

(# of Surface) * (One Revolution Time)

Instantaneous Buffer-Host Transfer Rate (Mbyte/sec) defines the maximum data transfer rate on AT
Bus. It also depends on the speed of the host.

The measurement method is given in 3.3.5, “Throughput” on page 13.
